Partilha USB a partir da velocidade do Android limitada

Question

Estou instalando o Ubuntu 14.10 na estação de trabalho.

Desde que eu não tenho cartão wi-fi, estou usando meu companheiro huawei para tethering usb. O telefone é Android kitkat 4.4.2

Network-Manager configura a conexão corretamente, o estranho é que a velocidade de download sobe para 40KB / sec MAX. Na verdade, não há outros processos levando largura de banda, seja no telefone ou no PC. A mesma coisa acontece no fedora 20. A velocidade de conexão do win é de 300 KB / seg. O mesmo no OSX e no telefone.

Como você pode ver, estou em um caminho para instalar, mas com essa velocidade está demorando para sempre

Answer 1

Aviso: Esta não é uma solução usando sua configuração existente, mas pode muito bem funcionar

Você já tentou usar o aplicativo PdaNet + ? PdaNet + contém tanto PdaNet quanto FoxFi. Eu não usei nem em cerca de um ano, mas quando eu estava ausente para trabalhar e ainda tinha dados ilimitados (com a Verizon), a FoxFi me ajudou a usar meu telefone como um hotspot sem nenhuma taxa adicional de hotspot. Eu usei mais de 60 shows por mês sem que minha largura de banda fosse limitada também. No LTE eu estava recebendo mais de 25 mbps.

Nota: PdaNet + e FoxFi só funcionam com telefones Android, mas vejo que você está coberto lá. Além disso, se o seu telefone não tiver a capacidade de suportar o recurso de hotspot, você também poderá usar o tethering via USB com o PdaNet +

Você pode obter o aplicativo aqui: PdaNet +

    

Answer 2

Bem, algumas perguntas me vêm à mente, mas vou dar uma cutilada nisso.

1. Quando você disse que obtém grandes velocidades no Windows, foi com esse mesmo computador?

2. Você tem um firewall como o UFW ativado? sudo ufw status dirá se ativado ou não. Se estiver, tente desativá-lo para ver se a velocidade melhorada é sudo ufw disable .

O que eu acho que o problema real é

Você tem um monte de dispositivos USB conectados olhando pelo seu registro e o USB tem tanta largura de banda. Estou no celular, por isso não consigo ver sua postagem enquanto digito, mas acho que vi algumas unidades USB diferentes, bem como um teclado e mouse e algum tipo de dispositivo Bluetooth USB.

Desconecte todos os dispositivos USB, exceto o teclado, o mouse e o telefone, e veja se consegue velocidades melhores.

Eu acho que já vi um hub USB em algum lugar também. Em caso afirmativo, o telefone está conectado ao hub ou à porta USB real no PC?
